Interactive 3D Restaurant Scene

A photorealistic 3D outdoor restaurant environment built with OpenGL and C++, featuring high-resolution shadow mapping, procedural wind animation, multi-source lighting, and comprehensive collision detection.

Overview

An immersive 3D garden restaurant scene with interactive navigation. The environment includes a restaurant house with 12 food presentation tables, each with individual spotlight illumination. Features animated trees with procedural wind shaders and a complete collision system.

Key Features

Advanced Rendering

• High-resolution shadow mapping (16384×16384)
• 12 individual spotlights with quadratic attenuation
• Directional lighting with configurable rotation
• Phong shading (ambient, diffuse, specular components)
• Alpha testing for foliage transparency

Procedural Animation

• Wind shader system using three combined sinusoidal waves
• 31-frame door animation (50 FPS)
• Synchronized shadow pass for animated elements

Interactive Elements

• Food information posters (press R near tables)
• Relaxation furniture interaction (press H to sit)
• Animated door (press O to open/close)

Navigation & Physics

• AABB collision detection for all objects
• Free camera control with WASD + mouse
• Pitch limiting to prevent gimbal lock
• Infinite dynamic terrain with tile-based rendering

Technical Implementation

Graphics Pipeline

• Model Matrix: object positioning/rotation/scaling
• View Matrix: camera position/orientation
• Projection Matrix: perspective (45° FOV, 0.1-100 clip planes)
• Normal Matrix: inverse transpose for correct lighting

Shadow Mapping

• Depth Pass: 16384×16384 framebuffer, orthographic projection
• Rendering Pass: Shadow map comparison with 0.005 bias

Procedural Wind Algorithm

wave1 = sin(time×1.5 + pos.x×2.0 + pos.z×1.5) × 0.5
wave2 = sin(time×2.3 + pos.x×3.0) × 0.3
wave3 = cos(time×1.8 + pos.z×2.5) × 0.2
heightFactor = smoothstep(0.3, 1.0, vertexHeight)
windEffect = (wave1 + wave2 + wave3) × heightFactor × strength

Infinite Terrain System

• Dynamic tile-based rendering (10×10 unit tiles)
• Centered on camera position
• Seamless texture alignment
